1 25 Claims.

This invention relates tofastening-inserting machines, the present application being a division of a copending application for Letters Patent for improvements in Machines for use in the manufacture of shoes, serial No. 568,964, filed on December 20, 1944. The machine shown in that copending application is a toe-lasting machine having wipers which wipe the margin of the toe end of a welt shoe upper into lasted position against a lip on the insole in the course of a cycle of power operations of the machine resulting from actuation of a clutch, means for applying a wire binder about the toe against the margin of the upper also in the course of the cycle of operations, and fastening-inserting mechanisms which during a pause in the cycle fasten the binder at the opposite sides of the shoe respectively by inserting fastenings in the margin of the upper and the lip of the insole in directions widthwise of the lip. The present invention .relates more particularly to the fastening-inserting mechanisms certain novel features of which are applicable to other uses than the fastening of binders.

As applied to mechanism for inserting a fastening in the margin of an upper and the lip of an insole in a direction widthwise of the lip the invention, in one aspect, provides a novel construction such that prior to the insertion of the fastening the fastening-inserting mechanism is moved heightwise of the shoe to a position determined by the shoe. As herein illustrated, the mechanism comprises a throat member for guiding the fastening, a driver for driving it and an anvil for clinching the fastening on the inner side of the lip, these parts bein movable as a unit to positions determined by engagement of the anvil with the insole, after which the throat member and the anvil are moved toward each otherto clamp the margin of the upper and the lip between them prior to the driving of the fastening. The construction shown is further such that the fastening utilized is a staple which, after the positioning movement of the mechanism heightwise of the shoe, is formed by means 010- erative in response to resistance of the shoe to further movement of the mechanism.

In accordance with another feature the invention provides, in staple-forming and driving mechanism; novel means whereby wire for use to form a staple is fed by movement of the mechanism to position it relatively to the work. In the illustrated embodiment of the invention the means for imparting the above-mentioned positioning movement heightwise of the shoe to the mechanism first moves a cutter into contact with the wire so that through such contact the wire is fed by the movement of the mechanism, after which the wire is cut and the staple is formed when the shoe prevents further such movement. After the driving of the staple the mechanism is moved reversely along the wire and thus receives a length of wire for use in forming the next staple, such reverse movement of the mechanism being limited by engagement with the end of the wire which is so controlled as to serve effectively as the limiting means.

The invention further provides novel means for limiting the operative movement of the driver in accordance with the position of the throat member when in contact with the work. As illustrated, the throat member and the driver are operated respectively by different toggles, the toggle for operating the throat member having a further definitely limited movement after engagement of the throat member with the work, and such further movement of that toggle serves to adjust the driver-operating toggle to cause the driver at the end of its operative movement to be positioned in a definite predetermined relation to the throat member. In this manner insurance is afforded that the fastening will be driven precisely the desired distance into the work.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be mo e particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In view of the disclosure in the above-mentioned copending application of which this application is a division, the present description will be confined to such portions of the machine as it is necessary to refer to for an understanding of the invention. The welt shoe is positioned for the toe-lasting operation by a device 2 constructed substantially as disclosed in Letters Patent -No. 2,388,367, granted November 6, 1945,0nan

application of mine, this device being arranged to engage the bottom face of the toe end of the insole adjacent to its lip a (Fig. 12) to position the shoe heightwise and also to engage-the inner face of the lip at the end andthe sides of the toe to position it lengthwise and laterally. The shoe is thus positioned when it is presented to the machine by the operator, and shortly after the starting of the cycle of power operations of the machine by actuation of a clutch (not shown) it is clamped against the device 2 by a toe rest 4 which is moved upwardly into clamping position. To assist in controlling the shoe there is also provided a heel rest 6 (Fig, 1) which is moved rearwardly into engagement with its heel-end face early in the cycle. In the course of the cycle of operations alsoa pair of wipers .8 (Figs. 1 and .12) are advanced and closed to embrace the upper about the toe end of the last and are moved upwardly to wipe theupperheightwise of the last, after which they are further advanced and closed to wipe the marginal portion of the upper inwardly over thefeather and against the lip of the insole, thelip being supported against the inward pressure of the wipers by the device 2. In predetermined time relation to the operation of the wipers a wire binder w is applied about the toe end of the upper to:hold it in lasted position byimeans of a pair of, grippers It], one of which is shown in Fig. 12, the grippers pulling the binder inwardly under the wipers and'against'the upstanding margin .of the upper opposite the lip of theinsole. The binder having thus been applied and its opposite end portions having been positioned by the grippersin the angle between the feather and the lip of the insole beyond the ends of the wipers, the cycle of operations of the machine is automatically interrupted to permit the binder to be fastened to the shoe during a pause in the cycle.

For thus fastening the binder the machine is provided with a pair of fastening-inserting mechanisms which may be termed staplingunits, these unitsbeing operated to form staples and to drive them over the'binder and through the upstanding-margin of the upper and the lip of the insole in locations beyond 'theends of the wipers while the binder is held against the margin of the upper by the wipers. The two units are positionedat the front of the machineand are identical except for such differences as are necessitated by the fact that they operate respectively at the opposite sides of .theshoe. Each unitincludes a main bar [2. arranged to extend generally widthwise of theshoe and provided-near its outer end with a guideway l4 (Figs. 6 and 7) 4 in which is mounted a crosshead l6 formed on one end of a shaft it which is mounted to turn in a bearing 20 secured to one side of the frame of the machine. The bar I2 and the parts thereon may thus swing in directions heightwise of the shoe about the axis of the shaft 18 and may move relatively to the shaft in directions widthwise of the shoe. Slidingly mounted on the top of the bar I2 is a plate 22 which is confined on the bar by two screws 24 extending through slots 26 (Fig. 2) in the plate. Near its outer end the plate 22 has a downwardly extending arm 28 (Fig. 7) arranged to engage the bearing 29 and to be engaged on its outer side by the end of a screw 30 threaded in a member 32 which is secured to the lower face of the bar 12. Connected to the outer end of the bar and to the frame of the machine is a spring 34 which tends to move the bar lengthwise in an inward direction, its inward movement being adjustably limited by engagement of the screw 3!! with the arm 28 of the plate 22. It will be understood that since the arm 28 is in engagement with the bearing 20 and since the plate 22 is'slidingly mounted on the bar l2, turning of the screw 39 serves to adjust the bar relatively to the plate in directions widthwise of the shoe as may be required by shoes of difierent widths.

Slidingly mounted in a guideway 35 (Fig. 8) in the inner end portion of the bar 52 is a stapleguiding throat or nozzle 38 which includes a small block 49 and another member 42 secured to the block and extending outwardly along the bar l2 beyond the block. Secured to the member 42 in spaced relation to the block 40 is a member M which serves as an outside former and by moving inwardly toward the shoe with the throat 38 forms a staple over an inside former 46 extending through a slot 48 (Fig. '7) in the member42. An enlarged portion of the inside former is slidingly mounted in an opening in one side of the bar l2 and in a cap member 59 secured to the side of the bar and extends into a slot 52 formed in one side of the member Q2. A spring 54 presses the inside former inwardly as far as permitted by its engagement with the member 42. Mounted in the space between the block 4!) and the outside former 44 is a small block55 which is positioned opposite the inside former (Figs. 2 and 4) when the parts are in their initial positions and is provided with a slot into which the staple forming portion of the insideformer extends. A pair of springs 58 positioned between the block 56 and the member 42 tend to move the'block in a direction away from the inside former and hold it initially in a slot 60 (Fig. 7) formed in a small plate 62 which by means of two screws 64 (Fig. 2) is secured to one side of the bar l2. With the block in this position a space is provided between it and the member 42 for the wire from which the staple is to be formed and for the bending of the legs of the staple about the inside former. In a manner hereinafter described the wire is fed into this space, between the outside former and one edge of the inside former, through a nipple 66 which is mounted in an opening in the bar 12. The length of wire required for the staple is severed from the rest of the wire, in response to movement of the'throat 38 and the outside former inwardly toward the shoe, by a cutter 68 which is fastened to the top of the outside former 44 and has a cutting edge substantially contiguous to the lower end of the nipple 86 when the parts are in starting positions. In .response to the movement of the throat and the outside former, as soon as the staple is formed, the inside former is forced outwardly by engagement of the member 42 therewith at one end of the slot 52 in this member to provide a clear path for a staple driven 10 which moves in guideways formed'in the members 40 and 44. Also in response to the same movement the block 56 is forced inwardly against the resistance of the springs 58 by engagement of the plate 62 therewith at one end of the slot 60 in the plate to close the space between the block and the member 42 and thus to assist in guiding the formed staple, the block being provided with a staple guideway arranged to aline with the guideways in the members 40 and 44.

Operative movement is imparted to the throat 38 and the outside former 44 through a toggle comprising a pair of links I2 and I4 which are connected together by a stud I5, the link I2 being connected to the throat and the outside former by a pin I8 carried by the members 42 and 44. As shown in Fig. 7, this pin has an opening through it for the'passage of the driver 10. The link I4 is connected at its outer end to a stud 80 mounted in a block 82 which is slidingly movable along a guideway in the bar I2 and is controlled by a spring 84 mounted in a cap 86 secured on the outer end of the bar. This spring normally holds the block 82 in a position determined by its engagement with a shoulder 88 (Fig. '7) on the bar I2. The link I4 is mounted on an eccentric portion of the stud 80, and the stud may be turned in the block 82for a purpose hereinafter explained. It is held in adjusted position by a nut 90 threaded on the portion thereof which extends through the block. The toggle I2, I4 is operated by fluid-pressure. means comprising a piston 92 vertically movable in a cylinder 94 fast on the front of the frame (Fig. 1). The piston is connected to a projection on the toggle link 12 at the knee of the toggle by a link 98 which is mounted at its upper end on a stud 98 (Fig. 3) in the piston and extends through a slot in the lower end portion of the piston. When fluid is admitted to the upper end of the cylinder 94 the piston 92 is moved downwardly against the resistance of a spring I connected to its loWer end and starts to straighten the toggle I2, I4, thereby imparting inward movement to the throat 38 and the outside former 44. Almost im-- mediately, however, the cutter 68 carried by the outside former engages the wire extending downwardly from the nipple 06, and the resistance of the wire prevents further straightening of the toggle. Continued movement of the piston, therefore, causes the bar I 2 and the parts thereon to swing downwardly about the axis of the shaft 6 which the binder w is located when the throat is at the limit of its inward movement.

As the throat and the outside former are thus moved inwardly the bar I2 is moved in an outward direction against the resistance of the spring 34 to bring the anvil I02 against the inner face of the lip of the insole as shown in Fig. 9. For this purpose there is pivotally mounted on a member I06 (Fig. 2) fast on the frame a lever I 08 the lower endof which is arranged to engage an upwardly extending arm I I0 formed on the inner end of the plate 22. The upper end of the lever is connected by a link I I2 to a pin I I4 (Fig. 3) in the piston 92. The connection between the link and the lever comprises a pin II6 carried by the lever and extending through a slot I I 8 in the link, the pin being engaged by a sprin I20 in the link. Accordingly the link acts on the lever to move the bar I2 in an outward direction, as above described, through the plate 22 the arm 28 of which is in engagement with the screw 30 on the bar, and after the anvil I02 engages the inner face of the lip of the insole the spring I20 yields to permit the link II2 to move relatively to the lever during further downward movement of the piston 92. As shown in Fig. 2, the lower end of the lever I08 is spaced initially from the plate 22 and its arm I I0 to prevent the outward movement of the bar I2 until after the anvil I02 ha substantially completed its downward movement. After the upstanding margin of the upper and the lip of the insole have been clamped between the throat 38 and the anvil I02, further straightening of the toggle I2, I4 serves to move the block 82 (Figs. 2 and 5) outwardly against the resistance of the spring 84. To limit the straightening of the toggle there is fast on the bar I2 a stop member I22 arranged to engage the toggle link I4, as shown in Fig. 9.

To insure that the portion of the binder adjacent to the throat 38 will be located in proper relation to the staple guideway in the throat, there is provided a finge I24 the inner end of which engages the binder underneath and lifts it to the proper height. This finger is pivotally supported at its outer end on the pin I8 through I8, and in this manner a staple-clinching anvil wire and to cause the outside former 44 to move inwardly and form a staple over the inside former 46. At the same time the throat 38 is moved inwardly toward the shoe until it engages the upper in the angle between the feather and the lip of the insole, as illustrated in Fig. 9, the end of the throat having therein a groove I04 (Fig. 8) in which the throat and the outside former are operated, and it is controlled by a pin I26 projecting from the throat member 40 in a manner which need not be herein further described but is fully disclosed in the copending application Serial No. 568,964.

The staple driver I0 is fastened to a driver bar I28 which is movable along the previously mentioned guideway I4 in the bar I2. The driver is operated through a second toggle comprising a' pair of links I30 and I 32 connected together by a stud I34, the link I30 being connected to the driver bar I28 by a. stud I36 which extends through 'a slot I38 (Figs. 7 and 8) in the bar I2. The link I32 is connected to the previously mentioned slidable' block 82 by a stud I40. The toggle I30, I 32 is operated by fluid-pressure means comprising a piston I42 (Fig. l) movable in a cylinder I44 which is integral with th previously mentioned cylinder 94, the piston being connected by a link I46 to a projection on the toggle link I30 at the knee of the toggle. The piston is moved downwardly against the resistance of a spring I48 connected to its lowe end. The fluid for operating the piston I42 i admitted to the cylinder I44 from the cylinder 94 through a port I50 when the piston 92 is moved downwardly from its starting position far enough to uncover this port. The piston I42 also extends upwardly initially beyond the port I50, and it is pulled downwardly against the resistance of the spring I48 to uncover the port by the previously described downward swinging movement of the bar I2, the bar acting on the piston through the toggle link I30 since the pin I36 connecting this link to the driver bar I28 is at that time at the outer end of the slot I38 (Fig. 7). It will be understood that by reason of the resistance of the spring I48 to the downward swinging movement of th bar I2 insurance is afforded that the cutter 68 will be forced against th wire as hereinbefore described through the toggle 12, 14 before the bar starts to swing downwardly. After communication is established between the cylinders 84 and I44 through the port I50 it is still necessary to prevent the driver from operating until the toggle 12, 14 has been substantially straightened to complete the forming of the staple and the inward movement of the throat 38. Temporarily, therefore, the straightening of the toggle I30, I32 is prevented even after the fluid is admitted to the cylinde I44. For this purpose there is pivotally mounted on a stud I52 on the bar I2 a stop member I54 one end of which is arranged to lie in th path of movement of the stud I36 and to engage that portion of the link I30 which is mounted on the stud. A sprin I58 mounted in a holder I58 which is fastened on a small cover plate I80 on the front of the bar I2 engages a tail I62 on the stop member I54 to hold the membe in that position. When the toggle link 12 nears th limit of its movement, a small block I84 carried by the link engages the stop member I54 and swings it downwardly against the resistance of the spring I58 out of the path of movement of the stud I35 and the link I30 (Fig. 9). This serves to release the driver-operating toggle to cause the driver to be operated by the fluid in the cylinder I44. The movement of the driver-operating toggle is limited by engagement of its link I30 with the stop member I22, as shown in Fig. 11.

Reference has been made to the fact that after the upstanding margin of the upper and the lip of the insole have been clamped between the throat 38 and the anvil I02 any further straightening of the throat-operating toggle, until its movement is stopped by the member I22, serves to move the block 82 outwardly along its guideway against the resistance of the spring 84. This block, therefore, assumes a position depending upon the position assumed by the throat in accordance with the thickness of the shoe materials between the throat and the anvil, and since the link I 32 of the driver-operating toggle also is connected to the block 82, this toggle is adjusted by the throat-operating toggle to determine the limit of the operative movement of the driver in accordance with the position of the throat. The staple-engaging end of the driver will, therefore, be located in a definitely predetermined relation to the throat 38 when the driver is at the end of its staple-driving movement. In the illustrated embodiment of the invention insurance is thus afforded that the driver Will not drive the staple too far with a possible tendency to cut the wire binder. By adjustment of the eccentric stud .80 the relation between the throat and the driver when these parts are at the limits of their operative movements may be varied to vary the distance thatthe staple is driven into the work. The anvil I02 has therein a clinching cavity I65 (Fig. 7) so arranged relatively to the driver as to deflect the staple legs in directions toward the 8 heel end of the shoe and outwardly into the lip of the insole, as illustrated in Fig. 12.

The wire W from which the staples are formed by the two stapling units is supplied from a pair of reels I88 (Fig. 1) rotatably mounted on brackets I10 which are secured to the front of the frame and passes over idler pulleys I12, portions only of which are shown, and thence downwardly to the respective units. Each strand of wire extends downwardly through a guide I14 fast on the front of the frame, and pivotally mounted on this guide is a bell-crank lever I16 (Fig. 10) one arm of which is arranged to engage the wire and to serve as a brake to prevent reverse upward movement of the wire while permitting it to be moved freely downward. A spring I18 acts on the other arm of the bell-crank lever to hold the first-mentioned arm in frictional engagement with the wire. Below the brake the wire extends through a flexible tube I which may be a coil spring and the lower nd of which extends into the previously mentioned nipple 86 and is held herein by a screw I82 (Fig, 4). The upper end portion of the flexible tube is mounted to slide freely in upward and downward directions in a guide I84 fast on the frame. As already explained, the first action of the toggle 12, 14 in response to the admission of fluid to the cylinder 94 is to move the knife 68 into engagement with the wire adjacent to the lower end of the nipple 68, after which the bar I2 is swung downwardly to carry the anvil I02 into engagement with the insole before the wire is cut by further straightening of the toggle. This downward swinging movement of the bar, by reason of the engagement of the knife with the wire, serves to feed the wire for use in forming the staple to be driven in the next shoe. It will be understood that after the fastening of the binder each stapling unit is swung upwardly by the springs I00 and I48 upon release of the fluid from the cylinders 94 and I44, and since the wire is prevented from moving upwardly by the brake I16, the upward movement of the unit causes the wire to enter the space between the outside former 44 and the inside former 48 until its lower end engages the lower wall of the guideway 38 (Fig. 8) in the bar I2. In this operation the flexible tube I80 slides upwardly in the guide I84. The end of the staple wire thus serves as a stop to limit the upward swinging movement of the stapling unit, and insurance is thereby afforded that the proper amount of wire to form the staple is fed to the unit. It will be evident, however, that the wire cannot enter the space between the inside former and the outside former until after the staple driver and the outside former have been retracted by their operating toggles upon release of the fluid from the cylinders 94 and I44, The engagement of the end of the wire with the top of the knife 68 prevents the upward swinging movement of the unit until the driver and the outside former have been thus retracted.

Leading to the upper ends of the cylinders 94 and I44 respectively are conduits I80 and I88 for operating fluid, preferably oil, under pressure. These conduits are controlled by automatic valve mechanism (not herein shown) whereby the op -erations of the stapling units are initiated immediately prior to the previously mentioned pause in the cycle of operations of the machine and whereby the fluid is released from the cylinders after the driving of the staples to cause the units to return to their starting positions, as fully disclosed in the copending application Serial No. 568,964. In each conduit I88 is a check valve I which is normally closed to prevent the piston I42 from being operated by any fluid except that delivered from the cylinder 94 through the port I50 when this port is uncovered. The purpose of the check valve is to expedite the exhaust of the fluid from the cylinder I44 and to permit the exhaust of fluid in the upper end of the cylinder beyond the port I 50 in the return of the parts to starting positions.

The manner of operation of the machine, in so far as it is of interest with reference to the present invention, will now be briefly summarized, a complete disclosure of its operation as a whole being furnished in application Serial No. 568,964. The operator presents the shoe in the position determined by engagement of the shoe-positioning device 2 with the toe end of the insole, and then starts the cycle by actuation of the clutch, whereupon the toe rest 4 and the heel rest 6 are moved to their shoe-supporting positions. In the course of the lasting of the toe end of the shoe which then takes place the wipers 8 wipe the marginal portion of the upper inwardly over the feather and against the lip of the insole, and a wire binder to (Fig. 12) is applied about the toe in upper-holding position, the binder being pulled inwardly under the wipers and against the upstanding margin of the upper by a pair of grippers I0, one at each side of the shoe. The binder having thus been applied and being pressed against the upper by the wipers, the cycle of operations is automatically interrupted to permit the binder to be fastened to the shoe forwardly of the ends of the wipers during a pause in the cycle. Just prior to the pause in the cycle the operating fluid is admitted to the cylinders 94 through the conduits I86, the fluid in the conduits I88 also being subjected to pressure to hold th check valves I00 closed. The first effect of the fluid admitted to the cylinders 94, acting through the pistons 92 on the toggles I2, 14 of the stapling units, is to advance the outside formers 44 and their cutters 60 far enough to engage the cutters lightly with the staple-forming wire extending downwardly into the units, downward swinging movements of the units about the axes of the shafts I8 being yieldingly resisted by the springs I48. These springs are,

' however, weak enough to permit the units thereafter to be swung downwardly by further movements of the pistons 92 while further operative movements of the outside formers and the cutters are prevented by the resistance of the wire,

the cutters therefore acting to feed portions of the wire downwardly past the brake members I16 which thereafter prevent reverse movement of the wire. In this manner the anvils I02 of the stapling units are carried downwardly into engagement with the insole in locations farther inwardly than its lip to position the units in proper relation to the shoe. By reason of the resistance of the shoe to further downward movements of the units the toggles I2, I4 are then further straightened to cut the wire, to operate the outside formers to form staples over the inside formers, and to move the throats 38 inwardly into engagement with the upper in the angle between the feather and the lip of the insole (Fig. 9) in locations between the forward ends of the wipers and the binder-holding grippers I0. At the same time the bars I2 of the units are moved in outward directions by the levers I08 to cause the anvils I02 to engage the inner face of the lip of the insole, so that the lip and the margin of the upper are clamped between the throats and the anvils. To insure that the portions of the binder engaged by the staples will be positioned in proper relation to the staple-guiding passageways in the throats, the fingers I24 are moved inwardly and upwardly to engage the binder underneath and to raise it to the proper height. After the throats have completed their inward movements, further straightening of the toggles '52, I4 serves to move the blocks 82 outwardly against the resistance of the springs 84, so that these blocks assume positions determined by the positions of the throats, the straightening of the toggles being positively limited by the stop members I22.

As the stapling units are swung downwardly in the manner above described, the driver-operating pistons I42 are pulled downwardly by the units to uncover the ports I50, and these ports also are uncovered by the pistons 92 in the downward movements of these pistons. This serves to admit operating fluid from the cylinders 04 to the cylinders I44. Operative movements of the staple drivers are, however, prevented by the stop members I54 until these members are displaced by the toggle links I2 (Fig. 9) near the end of the operative movements of the throatoperating toggles, whereupon the drivers are operated by the toggles I 30, I32. The staples are thus driven through the margin of the upper and the lip of the insole and their legs are clinched in directions toward the heel end of the shoe by th anvils I02 (Fig. 12). The straightening of the driver-operating toggles is limited by the stop members I22. Since the links I32 of the driveroperating toggles are connected to the blocks 82 which, as above described, are moved to positions determined by the positions of the throats 38 when the latter are in engagement with the upper, the driver-operating toggles are adjusted by the blocks so that the limits of the operative movements of the driversare determined in accordance with the positions of the throats. Insurance is thus afforded that when the drivers are at the limits of their staple-driving movements their end faces will be in a definitely predetermined relation to the ends of the stapleguiding passageways in the throats, which relation may be varied by turning the eccentric 'studs (Fig. 7).

Before the staple drivers complete their operative movements the grippers I0 are opened to release the binder in the manner disclosed in application Serial No. 568,964. After the driving of the staples the fluid is released automatically from thecylinders 94 and I 44 by the valve mechanism also fully disclosed in that application. The springs I00. and I48 then act to return the parts of-the stapling units to their initial positions relatively to one another and, as soon as the cutters 68 are retracted beyond the lower ends of the strands of staple-forming wire, to impart also to the stapling units their upward swinging movements about the axes of the shafts I8. The units thus move upwardly along the strands of wire, which are held against upward movement by the brake members I70, and they thereby receive the wire for use in forming the next staples, the upward movement of each unit being limited by its engagement with the end of the wire. Near the end of the upward movements of the units the clutch is automatically actuated to cause the machine to resume and complete its cycle of operations, as further disclosed in application Serial No. 568,964.
